K, so I have a r/c 4" lift with the typical torn drive shaft boot. 2 dr 6 spd. I wanna make it right and rock solid.

So I go buy a coast 1310 and some rk lower adjustables....seem to be good parts and not to expensive.

My question is, the control arms will roll the differential to fix the pinion angle correct? Will that position my 35's too far forward in my wheel well?
So do I need uppers as well to roll the dif back some? Are they necessary? Any info would be great. Or if there's anything else I should get to make it all worry free. Thank you.
I want the cheapest most reliable solution, as I'm sure most people do

 

Cheapest route is adjustable rear uppers. Using the lowers only will push the axle to far forward. The uppers need to be lengthened to fix the pinion angle by moving it up.

 

Oooooohhh, I thought it was the lowers I needed. So it is the uppers. So just the uppers should actually center my tires more so? I just want to be sure the driveshaft is working properly.
